  • Castelli Exclusive Alpha ROS Jacket

    Castelli's Exclusive Alpha ROS Jacket is perfect come rain or shine, using an advanced Gore® Windstopper® 150 fabric to keep out the elements. The outer wind/water protection layer is separated from the insulating layer, which ensures an excellent level of both ventilation and moisture management and perfect temperature regulation whether you're going fast or slow and whether it's wet or dry. 

    Thanks to innovative seam sealing at the shoulders, reduced seaming, and double stitching, the Alpha Ros provides effective rain protection to keep you mostly dry even on the wettest rides, all whilst offering highly efficient breathability. The tailoring is close but still allows freedom of movement thanks to light stretch and with a silicone waist gripper, the jacket won't ride up. 

    The ultimate in all-weather protection, the Exclusive ROS Jacket takes the guesswork out of what to wear, no matter what the weather conditions. It's a garment that can do it all and reduces the amount of kit needed to combat different conditions.
